Claims. ,tot .io- 401) The invention is most usefully employed when embodied in a `razor ofthe type which houses a stack of `blades in the handlefand is provided with an injector which successively feeds a blade at a :time from the stack intoa shaving head whichris pivoted at the end of the razor `usually on a post projecting therefrom, in such manner that it may be swung to a position with its blade-` retaining channel in line with the blade-ejecting orice of the `magazine for the reception of a blade, and transversely of the post for shaving. This general type of razor is illustrated and described, `for example, in Schick United States Patent No. 1,797,733. It is nevertheless adaptable to any `razor which possess the features of a blade-holding head which swings fromfone position to another abouta pivot.

The` broad object of the invention is to 4maire provision in a razor of this `type for accurately aligning the blade edge with respect to the guard with which such razors are conventionally pro` vided.` More particularly, `the object is to make provision in such a razor for stops against which the` blade edge abuts when in shaving position and fora `construction which will permit the reception of a blade` without Contact `with the stops while the head is imposition for receiving a blade from the magazine, but `whereby the blade edge will be automatically moved into contact with the stops and thus be accurately aligned with the guard when the head is swung to a position for shaving.

Referring to the drawing:

Fig. 3 is a View on the line 3-3 of Fig. 2 but showing certain of the parts in full;

Fig. 4 is a top view with the head in shaving position;

Fig. 5 is a view in elevation and in section through 'the median transverse plane of the shaving head.

Fig. 6 is an exploded view ofthe component parts ofthe shaving head.

Referring more in` detail to the drawing, the magazine handle of the razor'indicated by the numeral ID is provided with means for successively ejecting blade from a stack contained therein through the blade ejection slot Il, all of which is a well-known construction but, as an exampleof specific details of a suitable construction, reference is made to the above-mentioned United States patent to Schick No. 1,797,733. Since however the details of the magazine handle and the ejecting mechanism d-o not enter into the invention, I will not further describe them.

Proceeding to features which are` more closely involved in the invention, the head, the disassembled parts of which are illustrated in Fig. 6, is pivotally mounted on a king-post I2 projecting from the end of the magazine handle I0. In a magazine handle that is square in cross-section like that` illustrated, it is desirable for purposes of compactness of construction thatl the blade ejection orifice be parallel to and closely adjacent to one of the sides but, on the other hand, that, when the head is turned to shaving position as is shown in Fig. 6, the blade be inclined to the vertical axis of the post in order to facilitate use of the implement. Therefore, the pivotal mounting is on an axis that is oblique to the lines of the side walls as shown in Fig. 4, the degree of obliqueness being determined by the shaving angle desired in the particular case. A construction of this nature is shown in the United States Patent to Rodrigues No. 2,060,243, but, since it is not essentially involved in the invention, it will not be further described except to say that the obliqueness is such that, Whenthe head is in nonshavingiposition (that is, the position shown in Fig. 1), its blade-receiving channel is inregistry with the orifice and parallel `with the side of the handle, while in shaving position (as shown in Fig. 4), the bladechannel of the head is in. clinecl to the vertical axis of the post.

The blade receiving and holding channel is best illustrated in Fig.` 5, and its` main elements are the blade platform I3 and the spring clamping plate I4. The tension in the clamping platelll is, of course, properly adjusted to hold a blade A gripped between it and the blade platform with sucient rigidity and firmness to ensure proper shaving but not to a degree whereby undue resistance will be offered to movement of the blade toward the blade stops-all` of which will be presently further explained.

The actual overall Width of the blade receiving channel is determined by the relative positions ofthe blade stops I5, I5 on the one hand and the abutments I 6, I6 on the other, which, for convenience in manufacture, may be merely struck up from the blade platform. Of course, the spacing of the stops I5, I5 with relation to the abutments I6, I6 will be determined from the width of the blades which are to be used in the selected design and as will appear is to be greater than the blade Width.

VThe blade platform terminates in a suitable guard I8 and is cut away as shown at I9 to facilitate shaving and to allow for ready cleaning.

The blade platform and the spring clamping plate I4 may be assembled in any suitable way, but by way of illustration it may be done as shown in Figs. 5 and 6. In these figures the kingpost is provided with a pintle 20 on which is rotatably fitted a washer 2l having a reduced portion 22. The plate II is provided with an aperture 23 and the plate 2li, which is a continuation of the spring clamping plate I4, is provided wth an aperture 25, these apertures being of a size to rotatably fit the reduced portion 22 of the washer. The lever 26, which will presently be more particularly described, has anaperture 21 which loosely fits the washer 2| over its larger diameter. The whole is assembled in connection with the kingpost by means of the screw 28 and the washer 29 as shown in Fig. 6. The washer 29 is preferably provided with Vlugs 3G which enter slots 3| in the pintle 20. This isl to prevent back and forth turning of the screw when the head composed of the spring clamping plate I4, blade platform I3, and their connected parts are rotated abouttheir aXis for the purpose of changing fromshaving position to blade-receiving position, and vice versa. Y

, For greater firmness and rigidity of the head, it is best to extend the upper end of the kingpost so that, when the head is in shaving position, the blade platform bears on it as indicated by 32 in Fig. 5. If necessary for accuracy of registration of the blade-receiving channel with the blade ejection orifice, the material of therbottom plate may bestruck out the proper distance as shown by the numeral 33 for contacting with the kingpost at the point of registration.

The lever 25, as shown in the drawing, is in the form of a somewhat oblong washer or collar slightly bent on a transverse axis, thus providing bearing areas 34 and 34, wherebyV it may rock on the plate I1. When assembled, the plate II which is a continuation of the blade platform serves as a bearing surface for the bearing areas, and it will be apparent that, as the lever is rocked on these areas, the tip 35 moves toward and away from the stops I5, I5. The rocking motion of th-e lever is brought about by the travel of .the stud 35 about and on the lower arm 3'I of the lever,` the lower arm and the stud virtually constituting a cam and cam follower, respectively. As the shaving head is moved to blade-receiving this will be true of all blades that may be inserted in the head.

It is desirable that the lever possess some resiliency and that the arms be at such an angle and the other parts be so proportioned that, after the blade edge has abutted the stops (which should take place slightly in advance of full shaving position), further rotation to full shaving position will simply have the effect of pressing the blade edge firmly in abutment4 with the stops, without however imparting any motion to it.

A return motion of the shaving head from the position shown in Fig. 5 to that shown in Fig. l frees the blade from the pressure of the lever, and the entrance of a new blade from the maga- Zine simply drives out the blade already in the head, and the new blade is substituted for it,V

taking however the position shown in Fig. 2.

The blade platform is cut away as shown at 38 to provide an aperture in which the tip may travel toward and away from the stops. While I prefer that the lever be resilient as`I have before described, it is possible to make it rigid, ralthough obviously complete rigidity would introduce the necessity for a degree of precision in manufacture that would be a handicap to production on a quantity basis, and furthermore would serve no useful purpose.

While I have described a certain particular construction in which my invention is incorporated, I do not desire to be limited to this particular embodiment since many changes and modifications may easily be made without departing from the spirit and scope of the vinvention as positionv (as shown in Figs. l, 2, and 3), the stud passes the bearing area 34, thus leaving one arm of the lever and riding up on the next, thus causing the tip 35 to recede from the stops I5, I5 and thus substantially widen the blade-receiving channel to a width somewhat greater than that of the blade as shown in Fig. 2. The bladeejection slot IIl is so positioned with relation to the head, or vice versa, that the path of a blade as it emerges therefrom and enters the head takes the position shown in Fig. Z-that is to say, a position in which the edge of the blade is clear of the stops. The purpose of this is obviously to Vprevent Yinjury to the blade edge as it travels in the blade channel. When, however, the head is -'tipped to shavingposition'as shown in Fig. 5,

set forth in the following claims.
